Let's start with some mood boosters because this is a happy post for everyone, developer or merchant otherwise.
(Ignore the demon girl in a maid suit.)
Everyone probably doesn't know what had just recently happened, but let me tell you anyway.
Last May 15, 2021, Bitcoin Cash had a non-consensus upgrade that only had two things:
Multiple OP_RETURN outputs.
Removal of the 50-utxo chain unconfirmed limit.
But you might ask, where was the fanfare? The exchanges closing to prepare for it?
Let me answer your question with a question.
Why should they?
This upgrade is non-consensus in nature, and it solves some of the most annoying problems for services like read.cash, Satoshi Dice, and other sites that rely heavily on Bitcoin Cash.
Now, let's see why it's a boon and why it secures the network, specifically the side of 0-confirmations of Bitcoin Cash.
tl;dr - because everyone on the finance already did it via their payment processors
So, let's talk about the 50-utxo chain transaction limit for one last time.
The 50-utxo chain transaction limit, as it says, is a limit when you send transactions. Bitcoin Cash used to have a chain limit of 50 transaction outputs. The limit is due to a problem when calculating a way to speed up transaction propagation and it was used for Child Pays for Parent.
But now it's gone.
Now, you might wonder what's the other one. It's also simple to understand, and it's for developers, especially those who handle things like SLP tokens. With multiple OP_RETURNs, you can actually create a token, add some text on it, and also put a memo.cash post through it all at once. There is still a limit though, and that's a story for another time.
There's also the fact that outside these two, there are implementations of double-spend proofs for merchants that allow people to detect if someone double-spent. How they double-spent, considering that transactions are received based on a first-seen basis, plus they need miner coordination and also a semi-gullible merchant so...
So, what now, I guess?
Well, all the cryptocurrency market needs to know how is Bitcoin Cash lives, and it's a growing tumor of peer-to-peer cash users against the world of speculators. And keep sharing Bitcoin Cash and use it.
This is Rowan, singing off.
